Schedule a meeting with your supervisor and give a presentation. Be up front what the meeting is about. Make certain it is just you and them. Be as detailed as possible, and shove a 3 hour presentation into a concise 15 minute pitch. Be positive, but earnest in your concern. If this doesn't get things moving, explore your options, maintain a cordial relationship (never burn bridges), and quietly look for a better fit for YOU. Give your current employer as much notice as possible if things progress elsewhere. Upon leaving, keep your presentation for talking points later on for reference (remove proprietary info). Those talking points are your creative process. Harness that knowledge for future endeavors. Never stop growing, and don't let a cubicle stop you from progressing.
